To all whom it may concern: 1

Be it known that I, VVILHELM B. BRON- ANDER, a citizen of the United States, residing at Montclair, county of Essex, and State of'New Jersey, have invented a new and useful Improvement in Cigar-Bunch- Char e F ormers, of which the following is a specification.

This invention relates to a cigar bunch charge former, particularly, but not necessarily, adapted for use in connection with a bunch rolling mechanism in which charges of filler are fed along a table to an element of the rolling mechanism and then lowered with said element into position to be rolled into a bunch.

The main object of the invention is the production of a machine for converting substantially flat charges offiller into arcuate form before the bunch rolling begins. Another object is the production of a machine of this type in which the leaves of the charge are fanned out somewhat during the arcuate formation of the charge. It has been discovered that by so forming the charges just rior to rolling, bunches simulating the well nown Spanish bunches can be automatically produced, thus eliminating the necessity heretofore existing for manually spreading or fanning out the leaves on the rolling table, preparatory to rolling. With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically'set forth in the claims hereunto appended.

In the accompanying drawings, which' form a part of this specification and in which like characters of reference indicate the same or like parts, Fig. 1 is a front elevation of a device constructed in accordance with the invention; and Figs. 2 and 3 are detail fragmentary views illustrating certain parts of the device shown in Fig. 1 but indifferent positions.

In carrying the invention into effect, there is provided a suitable bunch rolling-mechanism including an element receiving a charge of filler in substantially flat form; and to coact therewith, there is further provided means acting on the charge to convert it into arcuate form before bunch rolling begins, inorder to pre are the charge to be rolled up from one 0 its edges as in a Spanish bunch. In the best constructions, there is further provided devices whereby the leaves of the charge of filler are spread or fanned out during arcuate formation.- The mechanisms, means and devices above referred to may be widely varied in construction within the scope of the claims, for the particular structure selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.

Referring to the drawings, 4 indicates a chianti belt forming a part of a bunch roll.- mg mechanism; 5 indicates the loop formingjelement of said mechanism; 6 indicates the belt tensioning device; and 7 indicates the bunch rollin table. Above the tensioning device 6, a eed table 8 is located along which charges of filler are fed by means of a plunger 9 having a reciprocating movement. The structure so far described is old andwell known in the art and a detailed description of the same bein unnecessary to a full understanding of t e present invention, it is omittedv in the interest of brevity and clearness'.

The chianti belt 4 lies over'a platen 10, also of well known construction, the purpose of the platen being to elevate the chianti belt to the level of the feed table 8 in order that it may receive a charge of filler tobacco in substantially flat form, and lower it into position for rolling within a binder to form a bunch. The platen 10 has a reciprocating movement and is cam actuated. With this end in View, it is mounted upon the upper end of a rod 11 sliding in bearings 12-13 formed on a bracket 14 mounted on a bar 15, the latter being suitably supported from the main frame of the cigar machine inconnec-- tion with which the device is used. The rod 11 is prevented from turning by'means of two slides 16 clamped thereon and engaging a suitable slideway v17 formed on the bracket 14: before referred to. The low-er end of the rod 11 is pivoted to the upper end of a connecting rod 18, the lower end of this connecting rod being pivoted to a cam lever 19 fulcrumed on a bar 20, extending across the machine. The cam lever 19 carries a cam bowl 21 tracking in a suitable groove in the'cam 22 fast 'on the cam shaft 23 which is oneof the main cam shafts of the cigar machine. It will be readily understood that the groove of the cam 22 is formed to produce the reciprocating movement of the substantially flat charge marked C, Fig. 2, a

7 little to one side of the middle thereof, for

a purpose which will presently appear. The follower 24 has a reciprocating, movement which is cam actuated. With this end in View, it is mounted upon the upper end of a rod 25, slidable in suitable bearings 26 and 27, formed on the bracket 28, fast to the bar .15 before referred to. The rod 25 is prevented from turning by a pair of slides 29 clamped thereon and engaging a slidewa 30 formed in the bracket 28. The lower end of the rod 25 is pivoted to the upper end of a connectin rod 31, and the lower end of this connectmg rod is pivoted to the free end of a cam lever 32,.fulcrumed on the bar 20 before referred to. The cam lever 32 carries a cam bowl 33 tracking in a suitable groove in the cam 34- fast on the cam shaft 23 before referred to. It will be readily understood that the groove of the cam 34 controls the movement of the follower 24 in proper timed relation with the movement of the platen 10 supporting the charge C.

Fig. 2 illustrates the platen 1O and'the follower 24 in the position they occupy when a charge has just been moved from the feed table 8 on to the chianti belt 4 overlying the platen. The platen and follower then move downward, the follower moving at a greater rate of speed than the platen in order to overtake the charge being lowered before the platen reaches its lowermost position. As the platen approaches the end of its downward movement, the loop is formed in the chianti belt, and the lower edge of the follower 24 engages the charge C to one side of its mid-section. A little further downward movement of its parts results in spreading or fanning out the leaves of the charge C and in simultaneously converting said charge from its initial substantiall fiat form to the arcuate form as clearly siown in Fig. 3. As soon as this is accomplished, the follower 24 is given a rapid upward movement so that the loop forming roller 5 can come into action and roll the charge. lVheu the charge is disposed, as shown in Fig. 3, the rolling begins at one edge of the charge, as in a Spanish bunch, so that when the bunch is completed the several leaves of the charge arev rolled up in spiral form within the binder. In this way a bunch is roduced which simulates the well known panish bunch; and this eliminates the necessity heretofore existing for mamr a cam-actuated reciprocatin ally spreading or fanning out the leaves of the char e on the rolling table when a Spanish bunch is to be made.

What is claimed is:

1. In a cigar machine, the combinat1on with bunch-rolling mechanism including an element receiving a charge of filler in substantially flat form, of means acting on the charge at one side of its center to fan out and convert it into arcuate form before bunch rolling begins, said element being in the form of a chianti belt, and said means acting on the charge during the formation of the belt loop.

In a'cigar machine, the combination with bunch-rolling mechanism including an element receiving a charge of filler in substantially fiat form, of means acting on the charge to' convert it into arcuate form before bunch rolling begins, said means engaging the charge at one side of its centre to fan out the leaves thereof during arcuate formation.

3.
